Description

Technical Field

[0001] This utility model relates to the field of asphalt recycling technology, specifically to an asphalt recycling roller that prevents material from sticking. Background Technology

[0002] Asphalt recycling involves sieving, heating, storing, and metering old asphalt mixtures removed from failed asphalt pavements, then adding them to the mixers of various asphalt mixing plants in different proportions. The mixtures are then uniformly mixed with the virgin material in the mixers to produce high-quality asphalt concrete.

[0003] In the asphalt recycling process, the asphalt recycling drum is one of the key pieces of equipment, responsible for heating the recycled wet material to a suitable temperature to remove moisture and other volatile substances. However, traditional asphalt recycling drums suffer from problems such as large heat loss, slow heating rate, and severe material sticking during the heating process, which affect production efficiency and product quality.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] (1) This utility model provides an asphalt recycling roller to prevent material from sticking. The recycling roller first knocks off the material blocks attached to the inner wall of the screening section through the material impact component and reduces the adhesion between the material blocks and the inner wall of the screening section, making it easier to clean the inner wall of the recycling roller when the inner wall of the screening section comes into contact with the shovel plate.

[0022] (2) This utility model provides an asphalt recycling roller to prevent material from sticking. The recycling roller is located in the impact area of ​​the impact block at the end of the first chain, and can collide with the shovel plate to clean the material attached to the shovel plate.

[0023] (3) This utility model provides an asphalt recycling roller to prevent material from sticking. The length of the first chain of the recycling roller is greater than the length of the second chain. The two chains are staggered on the second mounting arm, which can achieve a wider impact space and improve cleaning efficiency. Attached Figure Description
